Hi some one please respond.
cyg_io_write() is working fine but cyg_io_read() is blocking, as
per the reference manual cyg_io_read() echoes but here it is not
echoing.
Please find the code below.
Warm Regards

But unable to read from the terminal with echo using "cyg_io_read"
Please find the code sample

Char buff[] = "\nPlease enter some data: ";
retval = cyg_io_lookup("/dev/ttydiag", &handle);
if (retval != NOERR) {
printf("io lookup error: %d\n", retval);
return;
}
len = strlen(buff);
cyg_io_write(handle, buff, &len);
retval = cyg_io_read(handle,bufRead,&in_msglen);
if (retval != NOERR)
{
printf("Can't read data - DEVIO error: %d\n", retval);
while(1);/*Hang*/
return;
}
printf("Read %d bytes\n", in_msglen);
